Word to the wise-ass

Brad Pitt issues that warning to the "Guess Who" star during a celebrity-on-celebrity interview for the April edition of Interview magazine. "I remember two years ago you were after Clooney," Brad told Ashton. "I would tell you as your friend: Don't do it. Don't ever go near it.

"He'll kill you and everything you love. I know it's tempting, but don't do it."

Clooney is notorious in Hollywood for his gags, but even more for his reprisals against those who would dare prank him back--Pitt included.

Ash admits in the interview that there are four people who are off limits to "Punk'd"--and girlfriend Demi Moore is No. 1. "If something serious were ever to go down, like if something happens to one of the girls and I had to call Demi, I can't have been the boy who cried wolf," he says.
